Hey everyone, newbie here. I''ve been lurking around the forums for a couple weeks ago trying to soak up as much info as possible. This site is a really great resource, but I have question on a couple of round diamonds I am looking at. Diamond 1 is at a local store, diamond 2 is online. Diamond 1 is an "Ideal cut, hearts and arrows, but when I use the pricecope cut advisor I get a better score for diamond 2. Diamond 2 is about 1,500.00 cheaper. Is diamond 2 worth looking at? Any red flags I''m missing? Also diamond 2 show up low and left on the cut advisor graphic, what does that mean for the "brillance" factor? Thanks in advance for the help! :)



First diamond:
EGL-USA certified
1.39CT SI2
G
Depth:62.4
Table:57
Crown:15.4
Pav:43.6
Girdle: Medium to SL.Thick Faceted
Polish: Very Good
Fluoresence:Slight Blue
Symmetry: Excellent
Cute Grade: Ideal Plus (hearts & arrows)

Second diamond:
EGL-USA certified
1.5CT SI2
H
Depth:60.2
Table:56
Crown:14.5
Pav:41.4
Girdle: Thin toSL.Thick Faceted
Polish: Very Good
Flouresence:Medium Blue
Symmetry: Good
Cute Grade: (left blank)
 
Not liking both of these stones from the numbers.

The so call H&A is too steep in the angles and the other stone is much too shallow. Both will be ugly as a ring.

On the cut adviser, lower left means that it will have obstruction, meaning the light return from the stone will be block by the viewer especially up close, definitely not ideal for a ring, good for a pendant though.
 
Hi Jeremi

The first is what in PS speak is known as a steep deep with the angles, the second the pavilion angle is much too steep - pass on both of these, they aren''t good diamonds.

You mean the second pavilion is too shallow, right?
 
Thank you for the advice! I''ll keep looking, and using the cut adviser tool. I thought if I found an ideal cut I would be in the clear, but it doesn''t seem to be the case. Why are they calling diamond 1 an ideal anyway?

Thanks both of you for your help!

No idea. Not sure how they go about grading their H&A or their diamonds in cut''s criteria.

I was assuming it was an angle and % mix as these do crop up, if angle too steep - if % different story!

Jeremi, take all labels such as Ideal Cut, Premium Cut etc with a pinch of salt, especially if vendor applied these terms are no guarantee of a well cut diamond.

OP said is was lower left on the HCA chart, so I think the % number for the pav is correct.
 
Is there something I should be looking for on the pricescope search to narrow down my results for a well cut diamond? Or do I need to always request the certificate and enter the info into Cut Advisor.

BTW, here is what I''m looking for:

1.39-1.5ct round diamond
H or above
EGL USA or GIA certified
SI1/2 (eye clean)

I would be okay with a moderate blue flouresence, if it enhanced the brightness and didn''t create the milkey side affect.


Can I find a decent diamond for around $6,500? Or do I need to lower the ct weight?

Again, I appreciate you guys taking time to answer my newbie questions.

    Is there something I should be looking for on the pricescope search to narrow down my results for a well cut diamond? Or do I need to always request the certificate and enter the info into Cut Advisor. Use the search by cut option or for in house diamonds, many in house are sometimes well cut and as the vendor has them available, easier to get info on.

    BTW, here is what I'm looking for:

    1.39-1.5ct round diamond
    H or above
    EGL USA or GIA certified
    SI1/2 (eye clean)

    I would be okay with a moderate blue flouresence, if it enhanced the brightness and didn't create the milkey side affect. Medium/ moderate blue fluorescence will not have a negative effect on the diamond.


    Can I find a decent diamond for around $6,500? Or do I need to lower the ct weight? Personally I would, for that price it will be hard to hit 1.5cts and get a well cut eyeclean diamond.

    Again, I appreciate you guys taking time to answer my newbie questions.

Ditto above.

Also include AGS in the list of lab.
 
Wow! Those are great looking diamonds right within my price range. I really like the last one. I''ll contact JA to get more info. I really appreciate you taking the time to look those up, there are so many listings online it ends up being information overload trying to sift through it.

Ask JA for an Idealscope image for that one before commiting to purchase, they can provide one on request. Did you see this one out of SC's selections?

I just saw that, I think I will request an idealscope on those two. I''ll post them when I get them.

Ok keep us posted!

Will do! I put in the request and they said it could take up to 48 hours. Hey, I just found another on JA - let me know what you think. It's an SI2, but seems like a good price, and got a good grade on the Cut Advisor. Let me know if I'm learning? :)

http://www.jamesallen.com/diamonds/H-SI2-Premium-Cut-Round-Diamond-1253576.asp

Also, I went through all the ones I had marked as potential before I started speaking with you two and found this, it looks good on Cut Advisor too. It's about 1,000 less than the JA's we've been looking at, red flag?:

Weight 1.50 CT
Shape ROUND BRILLIANT
Color F
Clarity SI2
Measurements 7.33 x 7.29 x 4.47 mm
Depth 61.2%
Table 58%
Crown 13.3%
Pavilion 43%
Crown Angle 32.4°
Pavilion Angle 40.9°
Girdle MEDIUM TO SL. THICK FACETED
Polish VERY GOOD
Symmetry VERY GOOD
Fluorescence FAINT BLUE
Culet N/A
Cut Grade IDEAL PLUS

Cert: EGL-USA
 
Number looks good for both choices, if eye-clean. With the EGL, take into account that the color and clarity might be off.

Get IS image and then we can pick one from there.
 
H SI2 looks good, make sure it is eyeclean to your standards. With the second being EGL USA make any sale final on it checking out to your satisfaction ( and get this in writing) with an independant appraisal. Here is a tool you can use to find an appraiser in your area.
